BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to baseboards. More specifically, the invention relates to modular baseboard assemblies for use around walls and stairs.

2. Description of the Related Art

In recent years, the home flooring industry has expanded its number and styles of do-it-yourself flooring, allowing many homeowners to install attractive wood and tile floors themselves. The flooring technology has evolved to allow these wood and tile systems to be installed using as few specialized tools and materials as possible.

Most homes have baseboards that are secured to the bottom of the walls, above the intersection with the flooring. These baseboards are used to cover the joint between the wall and the floor, as well as to provide decoration. As homeowners are increasingly installing flooring themselves, they therefore must also install the baseboards themselves.

These do-it-yourselfers require baseboards that may be assembled easily and without requiring many specialized tools or materials. The homeowners may desire uniquely decorative baseboards, or simple traditional designs. Therefore, the baseboards should be modular to allow for different styles and designs of baseboards to be installed. The baseboards may be installed in rooms or along staircases.

Thus, an interlocking interior trim solving the aforementioned problems is desired.

SUMMARY OF THE INVENTION

The interlocking interior trim is a modular baseboard system that may be installed without using additional specialized tools or materials. The baseboard sections are stackable, and will connect to each other using tongue-and-groove or equivalent joints, before being secured to the wall using an adhesive backing or other common fastener. The interlocking trim is designed to allow the typical homeowners to install the trim themselves.

The interlocking trim can be used around the bases of walls of a room, as a chair rail, as crown molding or along a staircase, door or window. When used along a staircase, the sections are cut at an angle to allow the system to run parallel to the slope of the stairs.

These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is an interlocking interior trim, designated generally as 20 in the Figures. The interlocking interior trim 20 is a modular baseboard system that may be installed without using additional specialized tools or materials.

The interlocking interior trim 20 comprises a bottom baseboard piece 30, at least one center baseboard piece 40, and a top baseboard piece 50, as shown in FIGS. 1A and 1B. The baseboard pieces are stackable, and will connect to each other using tongue-and-groove or equivalent joints, before being secured to the wall W using an adhesive backing 22 or other common fastener. Referring to FIG. 6, the top baseboard piece 50 has an elongate tongue 52 protruding from its bottom surface 54. This tongue 52 may be inserted into a groove 42 on the top surface 44 of the center baseboard piece 40, as shown in FIG. 3, to secure the top baseboard piece 50 to the center baseboard piece 40.

The center baseboard piece 40 additionally has an elongate tongue 46 protruding from its bottom surface 48. The bottom baseboard piece 30 has a groove 32 running along its top surface 34, as shown in FIG. 2. The tongue 46 on the center baseboard piece 40 may be inserted into the groove 32 on the top surface 34 of the bottom baseboard piece 30 to secure the center baseboard piece 40 to the bottom baseboard piece 30. A second groove 36 may run across the lower front surface 38 of the bottom baseboard piece 30. A tongue 62 protruding from the rear surface 64 of a bottom quarter round piece 60, as shown in FIG. 5, may be inserted into the second groove 36, securing the bottom quarter round piece 60 to the bottom baseboard piece 30. The interlocking trim 20 is designed to allow the typical homeowners to install the trim 20 themselves due to the ease in snapping the tongue-and-groove connections together.

Referring to FIG. 4, the center baseboard piece 40 may optionally have an ornamental design 24 on its front surface 26. This design 24 may be a three-dimensional relief that is molded, carved, or otherwise formed into the front surface 26 of the center baseboard piece 40, or the design 24 may be printed, painted, etched, or otherwise adhered in two-dimensional form onto the front surface 26 of the center baseboard piece 40.

The top baseboard piece 50 also may optionally have an ornamental design 28. The design 28 may be printed, painted, etched, or otherwise adhered in two-dimensional form onto the front surface 56 of the top baseboard piece 50A, or the design 28 may be a three-dimensional relief that is molded, carved, or otherwise formed either into the front surface 56 of the top baseboard piece 50A, or the three-dimensional design 28 may encompass the entire top baseboard piece 50B, as shown in FIG. 7.

Additionally, a corner connector piece 70 may be used at the intersection of two walls to connect the sections of interlocking trim 20 installed at the base of each wall W. Referring to FIG. 8B, the corner connector piece 70A has a first slot 72 and a second slot 74 defined in its front surface 76. The first slot 72 is oriented such that it is normal to the second slot 74. The ends of the sections of interlocking trim 20 may be inserted into the first slot 72 and second slot 74.
